She walks 2 minutes for every 5 she runs. If she walks for 12 minutes how many minutes does she spend running?

ehidna [41]

Answer:

I believe it is, 30 minutes of running.

Explanation:

If she spends 12 minutes walking, that means she’s done 6 ‘sets’ of two minutes.

Then, you just have to multiply 6 by 5 and then you get 30.
